BEEFSTEAK-TENDERER.

--Be it known that I, GEORGE C. GIVENS, a

citizen of the United States, residing at Pea ,Beefsteak-Tenderor, of which the following is a specification.

The invention relates to improvements in best steak tenderers.

The object of the present invention isto improve the construction of beef steak tenderers, and'to provide a simple and comparatively inexpensive one adapted to be easily operated and capable of breaking the fibers or tendons of meat to tender the same, and of being easily cleaned after use.

With these and other objects in view, the invention consists in the construction and novel. combination of parts'hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claim hereto ap ended.

11 the drawing: Figure 1 is a plan View of a beef steak tenderer constructed in. accordance with this invention. Fig. 2 is a side elevation of the same. Fig. 3 is a longitudinal sectional view. Fig. 4 is a transverse sectional view. Fig, 5 is an enlarged detail sectional view taken substantially on the line XX of Fig. 4. Fig. 5 is a detail sectional irriew taken substantially on the line 'y y of Like numerals of reference designate corresponding parts in all the figures of the drawing.

The frame ofthe beef steak tenderer,

which may be constructed of either metalor a combination of wood and metal, embodies a horlzontal base 1, and vertical sides? rigid with and extending upwardly from the base at the opposite side edges thereof. The sides 2 are provided with hinged upper sections 3 connected at the rear edges of the sides with the lower rigid sections by suitable hinges 4 and detachably secured at the front by means of screws 5, which engage forwardl-y projecting ears 6 and 7 of the upper and'lower sections of the sides as clearly illustrat'edin Figs. "2 'a'i1d'3 of thefdrawing.

The upper and lower sections of the sides of the frame are provided at their'edges with metallic marginal strips or bars. The contiguous terminals of the bars are provided at the rear edges of the sides with eyes to form the said hinges 4, and they are extended at Specification of Letters Patent.

the front edges ofthe sides to form the said lugs 6 and 7. The lower seetionsof the sides are provided with opposite bearings for the journals 8 ofa-lower roll 9, and the upper sections 3 are-provided with vertical slots or openings 10 for the journalsll of the upper roll. 12. The. lower roll is providedwith longitudinal grooves and ribs, and the upper roll is corrugated to form annular grooves or ribs as clearly illustrated in Fig. 4 of the drawing. These rolls'are adapted to crush the meat and break the fibers. or tendons, and they thereby render the tough portions of meat tender.

The journals of the upper and lower rolls are equipped with gears 13, each rovided with two sets of teeth 14 and 15, t 1e inner teeth 15 being arranged opposite the intervals between the outer teeth, and connected with the same by a central annular web 15". The teeth are rounded and owing to their double alternate arrangement a positive ro tary movement of both the upper and lower rolls is secured when the said rolls are spaced at dilierent distances apart. One of the journals of the lower roll is provided with a crank handle 16, by means of which the device is operated. The desired pressure is applied to the rolls by means of adjusting screws 1-7, mounted in threaded perforations 18 of the metallic m arginal stri s or bars of the upper sections 3 of the si es, and extending downwardly into the slots 10 from the upper ends thereof, and provided at their lower ends with balls 19. The balls 19 are arranged in sockets 20 of plates 21, which engage the terminals of a transverse bar 22, and the latter is secured by suitable fastening devices 23 to a pair of bearing blocks 24. The

dsearing blocks 24, which engage the journals of the upper roll operate in the slots 10, and they are provided at their side edges with longitudinal ribs 25,-which are arranged in grooves 26 of the walls of the slots 10 whereby the said bearing blocks are interlocked with the upper sections 3 of the sides of the distance of the lower roll. The sides of the outer faces of the lower sections of the sides ping around the same.

table extend laterally beyond the reduced inner portion and are provided with upwardly extending arms 30, having attached flanges 31, which extend beneath and are secured to the lower face of the table. The shoulders formed by reducing the inner portion 28, engage the lower sections of the sides; and cooperate .With the arms to rigidly support the table in position for use. The upper ends of the arms are secured to the of the table by suitable fastening devices 32 forming ivots and ermitting the outer portion of t e table to e swung upward.

The meat tenderer is provided in rear of.

the rolls with'an inclined plate or member 33 extending downwardly from the lower roll and adapted to prevent'the' meat from wrap- The fixed plate or member 33, which extends across the space between the sides of the frame is rigidly connected with the latter. Themeat is placed upon the table, and is fed between the rolls, and is delivered upon the inclined-plate'or member.

Havin thus fully described my invention, what I c aim asnew and desire to secure by Letters-Patent" is A beef steak'tenderer comprising a frame embodying a base, and opposite sides provided with vertical slots and having separa- 'ble upper and lowefsections, metallic bars secure "to the side edges of the sections and provided with hinge joints at the rear edges of the sides and extended at the front of the same to form pairsof projecting lugs, means for' detachably securing the lugs together,

bearing blocks engaging the upper roll, a bar
